“Gedolei hador cannot be influenced by the tides of outside, alien philosophy.”
1) That’s a load of garbage. Many great Torah scholars and leaders throughout history were influenced by and sided with secular philosophers on many issues.
2) You imply that any philosophy coming from “outside” of Jewish origin is automatically wrong, which is garbage.
3) By making such a ridiculous statement, you automatically disparage all great Torah scholars who are also well versed in philosophical areas.
4) You aren’t a gadol hador, and therefore it isn’t up to you to decide what is a prerequisite of achieving that title.
